I am working in InDesign 18.5.0.57 on a 2019 MacBook Pro running Ventura 13.3.1.
I have three external monitor, two 24-in. DELL monitors, and one 25-in. ASUS monitor, configured as InDesign-Tool-Flyout-01.jpg shows.

My problem is the InDesign tool flyout menus popup on my laptop screen rather than the center upper monitor as shown in InDesign-Tool-Flyout-02.jpg

I know that the flyout menu can show up on the center upper monitor because it has in the past. This problem showed up after upgrading to OS 13 and InDesign 18. This has happened to before with InDesign 17, but was solved -- I can only surmise -- when I my OS was upgraded.

So I'm not sure if this is an Adobe problem or Apple problem, or both, but it appears that one should upgrade the Mac OS before upgrading InDesign?

It is not threatening my productivity, other than the inconvenience of have to mouse down to the laptop to select the proper tool, but it annoys me.

I'd rather not bother IT with uninstalling and reinstalling InDesign, since we are a rather large and diverse company, and it would seem insignificant to our powerful IT overlords.

Any help would be appreciated.

Thank you
